How manageable are the 200-level classes?
The 200-level classes are just the next step up in your education. As long as you feel confident in the skills taught in the 100-level sequence, you should be ready for 200-level classes. In the 100 level classes, a wide range of experience is evident, but this is not as prevalent in the upper levels. Most people have never studied ML or C, so 15-212 and 15-213 provide an even ground for the class.
